Detecting wireless noise within time period in which no data is purposefully wirelessly communicated

1. A method comprising: driving a liquid crystal display (LCD) at a first driving frequency; transmitting data at a data frequency within a first data frame of a plurality of data frames specified by a communication protocol; stopping transmission of the data when the first data frame has finished even though additional data is to be transmitted; before a second data frame of the plurality of data frames has started, detecting whether wireless noise is present at the data frequency, within an inter-data frame period specified by the communication protocol; in response to detecting that the wireless noise is present at the data frequency, driving the LCD at a second driving frequency lower than the first driving frequency; transmitting the additional data at the data frequency within the second data frame; stopping transmission of the data when the second data frame has finished; before a third data frame of the plurality of data frames has started detecting whether the wireless noise is still present at the data frequency, within another inter-data frame period specified by the communication protocol; in response to detecting that the wireless noise is no longer present at the data frequency, continuing to drive the LCD at the second driving frequency; and in response to detecting that the wireless noise is still present at the data frequency, again driving the LCD at the first driving frequency.

2. The method of claim 1 , wherein the protocol is an orthogonal frequency division multiplexing (OFDM) protocol defining one or more inter-frame space (IFS) periods.

3. The method of claim 2 , wherein the OFDM protocol is part of the IEEE 802.11g protocol.

4. The method of claim 1 , wherein data is wirelessly communicated using an antenna that is proximate to the LCD, such that a clock frequency at which the LCD is being driven causes harmonics within a frequency range at which the data is being wirelessly communicated, such that driving of the LCD causes the wireless noise.

5. The method of claim 4 , wherein detecting the wireless noise comprises determining that a level of the wireless noise exceeds a predetermined threshold.

6. The method of claim 1 , wherein detecting the wireless noise comprises recording the wireless noise.

7. A computing device comprising: a liquid crystal display (LCD); an antenna; a wireless communication mechanism to wirelessly communicate data over the antenna; and, a wireless noise-reduction mechanism to: drive the LCD at a first driving frequency; transmit data at a data frequency within a first data frame of a plurality of data frames specified by a communication protocol; stop transmission of the data when the first data frame has finished even though additional data is to be transmitted; before a second data frame of the plurality of data frames has started, detect whether wireless noise is present at the data frequency, within an inter-data frame period specified by the communication protocol; in response to detecting that the wireless noise is present at the data frequency, drive the LCD at a second driving frequency lower than the first driving frequency; transmit the additional data at the data frequency within the second data frame; stop transmission of the data when the second data frame has finished; before a third data frame of the plurality of data frames has started, detect whether the wireless noise is still present at the data frequency, within another inter-data frame period specified by the communication protocol; in response to detecting that the wireless noise is no longer present at the data frequency, continue to drive the LCD at the second driving frequency; and in response to detecting that the wireless noise is still present at the data frequency, again drive the LCD at the first driving frequency.

8. The computing device of claim 7 , further comprising a bezel within which the LCD is disposed and within which the antenna is disposed, wherein the LCD is driven at a frequency that causes harmonics within a frequency range at which the data is being wirelessly communicated, such that driving of the LCD causes the wireless noise.

9. The computing device of claim 8 , wherein the wireless noise-reduction mechanism is to detect the wireless noise as exceeding a predetermined threshold.
